There are signs young people are getting more politically engaged. DeWitt said more people registered to vote through Rock the Vote's online platforms last week — some 50,000 — than in any other week this year.
The organisation's social media accounts had as many impressions between Monday and Friday of last week as it typically has in an entire month, with more than 1 million.
"It will just be incredibly important to us to make sure we're protesting now and voting later," DeWitt said.
That is not assured. The coronavirus pandemic has halted traditional campaigning as well as big concerts and festivals, the kinds of places where campaigns and groups like Rock the Vote and HeadCount typically recruit young voters. On top of that, lawmakers' efforts to change voting laws in some states could restrict younger voters like college students.
Joe Biden's Democratic presidential campaign is banking on these voters supporting him when the choice is a binary one between Biden and Trump. But that is not guaranteed.
"Our bar can't be: Are you better than Trump?" said Cliff Albright, a co-founder of Black Voters Matter, which works to register voters and organise black communities. "For folks who are angry, who are in the streets, or who are at home and not engaged, you just telling me you're better than this nut — that's not enough."
Many young people are still unfamiliar with Biden, "and they certainly don't know where he stands on issues," said Heather Greven, spokesperson for NextGen America. The group plans to spend at least US$45 million to target young voters in battleground states.
Biden said during a recent virtual fundraiser that he thought the protests will energise young people to turn out for him. "Now they are engaged," Biden said. "They feel it. They taste it. And they're angry and they're determined."
His campaign hasn't made major changes to its youth outreach amid the protests, which started after a white Minneapolis officer pressed his knee into the neck of Floyd, a black man who was handcuffed and crying out that he couldn't breathe.
Instead, Biden has stuck largely with an initiative known as "League 46" that combines groups such as Students for Biden and Young Professionals for Biden.
In an effort to appeal to younger, liberal voters, Biden has put progressive Representative Alexandria Ocasio-Cortez on a climate change task force. But he doesn't support some of the proposals that energised supporters of his primary rival Senator Bernie Sanders such as "Medicare for All."
Ja'Mal Green, 24, an activist in Chicago, said he and other young people were disappointed by Biden's rejection of a call to "defund the police," which has become a rallying cry for protesters.
The former Vice-President said that an overhaul of policing is needed but can be done by putting conditions on federal funds.
That position may reassure older and moderate voters who helped Biden win the nomination, Green said, but young people want to see more change.
"If not, they'll just say 'to hell with the election,'" he said.
Many of the young people taking to the streets are focused on public officials with a more direct impact on their lives such as mayors, police chiefs and district attorneys because "they see that's where the change is," said Green, a Black Lives Matter leader who joined protesters in Minneapolis.
There were also protests in Louisville, Kentucky, over the death of Breonna Taylor, a 26-year-old black woman fatally shot by police in her home in March.
Tom Bergan, 22, attended a protest last week in Louisville, where he is a HeadCount field organiser.
In pre-pandemic days, HeadCount focused on registering young people at concerts and festivals, but that's shifted to more online organising since Covid-19.
For the protests, Bergan printed off large QR codes that he hoisted on a poster board. Anyone who scanned the code on their phone was connected to an online voter registration page.
Bergan said the crowd was enthusiastic, with many already registered to vote, and much of the conversations were around Taylor's death and local changes such as the decision to limit no-knock warrants.
He said the moment reminds him of 2018, when he volunteered with HeadCount during a March for Our Lives in St Louis, as thousands of young people turned out in cold, rainy weather.
That northern autumn, turnout among voters ages 18-29 was nearly double what it was in 2014, with 28 per cent of eligible young voters casting ballots, according to CIRCLE, the Centre for Information and Research on Civic Learning and Engagement at Tufts University.
They were much more likely to support Democratic than Republican congressional candidates, 64 per cent to 34 per cent, according to an AP VoteCast survey of more than 115,000 Midterm voters nationwide.
That turnout is still less than in 2016 or 2012, presidential election years when about 45 per cent of young voters turned out, according to CIRCLE, a drop from 2008, when Barack Obama was on the ballot and turnout soared to a level not seen since 1992.
Will 2020 bring another peak?
"That's the big 'if,' and we don't really know until November," Bergan said.
